Drill Attachment Adapter for Universal Drill Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drill attachments face challenges in securely engaging with different types of drill apparatuses, as they often lack standard engagement points, making it difficult to operate comfortably, especially when drilling in concrete, which requires prolonged physical effort.
Innovation Solution
The development of a drill attachment with an adapter component that includes an upper and lower clamp member, allowing universal engagement with various drill apparatuses, enabling remote actuation of the drill trigger through a trigger actuator, and a bifurcated frame for secure coupling, reducing the need for direct manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drill attachment is designed to securely engage with drill apparatuses, then the reliability of the engagement is improved, but the device complexity increases due to the need for adapter components and multiple engagement mechanisms
Solution Approach 1:
The adapter component is designed with a universal interface that can engage with multiple types of drill apparatuses (e.g., SDS-plus, SDS-max, straight shaft drills) through a single standardized connection mechanism. This allows the drill attachment to function with various drill types without requiring multiple specialized engagement mechanisms, thereby improving reliability while controlling complexity.
Solution Approach 2:
The adapter component serves as an intermediary element between the drill attachment and the drill apparatus. It mediates the connection by providing a standardized interface that translates between different drill apparatus configurations and the attachment's engagement requirements, ensuring reliable connection without complicating the attachment's core structure.
2Ease of operation
If the drill attachment requires specific engagement points on the drill apparatus, then the ease of operation is improved through secure positioning, but the adaptability deteriorates when working with different types of drill apparatuses
Solution Approach 1:
The adapter component incorporates a universal engagement interface that can accommodate multiple drill apparatus types (SDS-plus, SDS-max, straight shaft) through a single design. This maintains stable positioning and ease of operation across all compatible drill types without requiring drill-specific attachment configurations.
Solution Approach 2:
The adapter component includes movable or adjustable elements that can adapt their configuration based on the specific drill apparatus type being used. This dynamic adjustment capability allows the attachment to maintain secure positioning and ease of operation while being compatible with various drill apparatus configurations.
3Device complexity
If the user must directly actuate the drill trigger during operation, then the device complexity is reduced, but the ease of operation deteriorates due to physical exhaustion from prolonged kneeling or sitting
Solution Approach 1:
The drill attachment incorporates an automatic trigger actuation mechanism that uses the drill's own operational parameters (e.g., forward motion, drilling resistance) to automatically activate the trigger. This eliminates the need for the user to manually hold and press the trigger, reducing physical exhaustion while maintaining simple overall device architecture.
Solution Approach 2:
The manual mechanical trigger actuation is replaced with an automated mechanism that responds to drilling conditions. This substitution eliminates the need for continuous manual mechanical input from the user, improving comfort during prolonged operation while keeping the control system relatively simple.

AI summary
A drill attachment for engagement and actuation of a drill apparatus having a bifurcated frame defining a first shaft and a second shaft operatively engaged to the drill apparatus at first and second engagement points is disclosed. A handle is pivotally engaged to the first shaft and is operatively coupled to a trigger actuator located along the first shaft through a trigger cable operatively engaged to a trigger actuator the distal end of the first shat that permits remote actuation of the drill apparatus. The trigger actuator includes a pivotable rocking arm having an actuator pad in selective engagement with the drill trigger such that actuation of the handle by the user pivots the rocking arm in a manner that causes the actuator pad to engage or disengage the drill trigger when operating the drill apparatus. The drill attachment is operatively engaged to the drill apparatus through an adapter component having a proximal portion engaged to the drill attachment and a distal portion defining a generally curved configuration adapted to engage the handle of any conventional drill apparatus.
